Application filed September 11, 1912. Serial No. 719,697.

To all whom, it may concern:

Be it known that I, WILLIAM H. HUNT, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certam new and useful Improvements in Coal- VVagons, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make and use the same.

This invention relates to coal delivery wagons or trucks, and the object thereof is to provide improved means for raising the.

body of a vehicle of this class into an elevated position to facilitate the'discharge of the coal therefrom, and the invention also involves an apparatus of this class by means of which the bed may be raised horizontally or evenly at both ends and the coal discharged from the central bottom portion thereof, or. whereby the front end of the body may be raised higher'than the rear end and the, coal discharged from said rear end thereof] The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters, in each of the views, and in which Figure 1 is a side view of a coal wagon or truck involving my invention and showing the bed in an elevated and horizontal p0 I sition;Fig. 2 a bottom plan view of the bed or body and showing parts of the hoisting or elevating apparatus connected therewith, part of the construction being in section;Fig. 3 a detail sectional view of a part of the hoisting or elevating apparatusshown in Fig. 1, part of the construction being in section ;-Fig. 4 a detail view of one of the hoisting lever arms which I employ ;'-Fig. 5 a front end view of a part of the body and showin one of the guides employed for holding sa d body in its proper position, when it is being raised or elevated;Fig. 6 a sectional detail view of a part of the hoisting or elevating apparatus shown in Fig. 2, and showing two different lever arms one of which is shown in Figs. 3 and 4, and ;-Fig. 7. a view similar to Fig. 1, but showing the front end of the'bed raised above or higher than the rear end, andshowing a modification of the hoisting or elevating apparatus.

In the practice of my invention, I provide,

seat a for the driver or operator of the vehiclei It must be understood however, that the truck frame a may be constructed in any suitable manner within the necessary limits fixed by the body hoisting or elevating apparatus hereinafter described. 1- have also shown at b a body,-the general form of which is similar to the bodies of other vehicles of this class, and the bot-tom of said body is provided centrall thereof with the usual discharge chute b in connection with which the usual detachable guide chutes are employed, and whereby the contents of the body 7) may be discharged laterally from one side of the truck or vehicle in the usual manner, said detachable guide chutes being not shown. The body of the truck frame is also provided at the front end thereof with vertical slotted guides 6 which are secured thereto, and the bottom of the bed is provided at the front end thereof and at the sides thereof with plates which are securedthereto and are provided with pins 2) which extend through the slots in the guides I) and are provided with nuts 7). The bed 6 is also provided at. the rear end thereof and at the sides thereof with vertical guides c which are secured thereto at and which pass downwardly through keepers 0 and a secured to the sides of the body of the truck,

and this construction serves'to guide and hold the bed I) in proper position, as it is being raised and lowered as hereinafter described.

The body of the bed involves a bottom frame consisting of parallel side bars (l, transverse front and rear end bars {1 and (l and centrally arranged transverse bars or?" and d between which the chute is located, and placed between the front end bar (1 and the central transverse bar (1" are parallel longitudinal bars d, and placed between the rear end bar 03 and the corresponding transverse central bar (2 are parallel longitudinal bars (Z Secured to the thetransverse bars (l and (Z are hanger plates 6 arranged in pairs, and these plates are provided in their inner end portions with longitudinal slots 6 through which are passed pins 6 on which are mounted lever armsv 6* having forked heads 6 through which the pins 6 pass, and in the outer end portions of the hanger plates (2 are transverse pins f on which are mounted lever arms f 'having forked heads f provided with central tongues f forming longitudinalslots f and the pins f pass through the sides of the forked heads f and through the tongues f, and the bars d and d are provided with central slots f in which the ends of the tongues fit and are movable.

The free ends o the lever arms f are provided with forked heads f and the free ends of the lever arms 6 fit in the forks of said heads, as shown at e, and passed through the forked heads f of the lever arms f and the free ends or heads. of the lever arms 6 are shafts 9 provided at their ends with flangedwheels g and mounted on the shafts 9, between the free ends of the lever arms and c are sleeves 3 on which are mounted yoke-shaped keepers 9 provided with pulleys g and secured to the bars d and d at g are chains or cables 9 which are passed around the pulleys g The main part of the truck frame a is provided centrally with a transverse winding shaft h with which the chains or cables 9 are connected and on which said chains I or cables are adapted to be wound, and the main part of the truck frame is also provided on the inner side of each side portion thereof with downwardly and outwardly inclined tracks or ways 71. on which the flanged wheels 9 on the ends of the shafts 9 rest, and said tracks or ways are preferably curved upwardly at their outer ends to form stops 71. 'which limit the outward movement of the shafts g and the levers e and f In the construction shown, the tracks or ways It at each side'of the track are. formed integrally or connected by a horizontal bar h.

The shaft h is provided on the left hand side of the truck with a large gear '5 which meshes with a pinion i mounted on a shaft 71 provided with a large gear 2" and adjacent to which is a crank shaft i provided with a crank 71 and a small gear or pinion i which meshes with the gear 71, and adjacent to which is a rock shaft i provided with a handle i and a pawl i which operates in connection with the pinion or gear 2" to prevent backward movement thereof.

It will be observed that both ends of the lever arms 6 are curved outwardly and this permits the separate pairs of lever arms 0 bars d and d adjacent to dotted .lines in crank i to the right when the body 1) 1S resting on the truck frame, said body may" body and truck frame may be of any and f? to lie closely together when the bedb is resting on the truck frame, as shown in Fig. 1, and by turning the be raised horizontally into the position shown in full lines in Fig. 1. At the beginning of this operation the pins e? which connect the lever arms 6 with the hanger plates 6 are in the outer ends of the slots '6 in said plates nism is operated and the body 1) begins to rise, the pins 6 slide inwardly in the slots 0 and the corresponding ends of the levers 0 move inwardly away from the levers F, as clearly shown in full lines in Fig. 1, and this operation continues until the bed 6 reaches the limit of its "upward movement when the pinse? reach the inner ends of the slots 6 and the bed 5 is securely held by the lever arms 6 and f and by the guide bars or device 6 and c in this elevated position, the levers e and f serving to brace said bed ag ainst forward and backward movement and the guide bars 6 and 0 against lateralmovement, and by reason of the particular construction and operation of the lever arms 6* and f and the method of connecting said arms with the hanger plates e; it will be understood that said lever arms also aid in bracing and holdingthe body against lateral movement.

It will be observed that the lever arms (3 are longer than the lever arms f and by connecting' th'e'front or lower ends of said lever arms at each end of the bed with the same transverse shaft and by connecting the chains or cables 1 with said shaftby means of the pulleys g and in the manner shown and described, the operation of the winding mechanism with which said chains or cables are connected is facilitated and the power necessary to operate said mechanism is reduced to a minimum.

In the construction shown, the guide bars 6 at thefront end of the main part of the truck frame are secured at their lower ends, as shown at b, and said guide bars are connected at the top thereof by a transverse rod b which gives strength and stability to said guide bars. the.usual manner, with a bottom which is inclined downwardly from both ends to the chute 6 as indicated in dotted lines at o but as hcreinbefore'stated the particular construction of the body I) and the truck frame forms no part of'this invention, and said preferred construction. l i I The construction'shownin Fig. 7 in which the body hoistingor elevating apparatus is designed to raise the front end of the body so as to discharge the coal from the rear end thereof is exactly the same as that shown in Figs. 1 to ,6 inclusive, except as follows. In

but as the winding mecha- '115 The bed- I) is also provided, in

this construction the hanger plates 6 are lengthened as are also the slots 6 therein, and a supplemental winding shaft j is mounted rearwardly of the main winding shaft h and loosely mounted on the shaft j is a large gear j similar to the gear 2' and meshing therewith, and the gear 7' and shaft j are provided with a clutch device 9' of, the usual construction and operated by aj' lever 7' whereby the gear 7' may be secured to and caused to turn or be turned with the shaft j, and the chains or cables which op with the compartment is. In this operation it is necessary to provide means to prevent the frontend part of the body from tipping down when the compartments Z2 and 70 have been emptied, and for this purpose I employ at the opposite sides of the truck frame and at. the front end thereof toggle levers m consisting of short members m pivoted to the side of the body of the bed at m and long members m pivoted or hinged to the parts m at on and also pivoted to the sides of the truck frame at m", and pivotally connected with the toggle levers m at the pivotal points m are link bars m which are pivot- I ed on or mounted on the pins 0 which pass through the slots 6 in the hanger plates 6 and hold the lever arms 6 in connection with said plates. With this form of construction when the bed Z) is in its lowest position and resting on the truck frame,the toggle lever devices m are folded inwardly of the top rails a of said truck frame and do not interfere with the operation of the lever arms 6 and f and with t is form of construction, when the bed is raised into the position shown in Fig. 7 or still higher, and the rear compartments 7: and It emptied, the front end of said bed will not. drop down I but will remain in the desired position until the entire bed or front compartment thereof is emptied. It will be understood that with this construction, when the clutch device 7' is in operation, the bed may be raised horizontally by operating the crank i, but when the clutch device 7'? is not in operation the I front end only of the bed will be raised by operating said crank and, in practice, it may be advisable to first raise both ends of the bed slightly and then throw out the clutch j and raise the front end of the bed to the desired extent and in order to prevent any backward movement of the bed in this operation, or any tendency of the bed to move backwardly, link braces 12. are pivoted to the bottom of the bed inwardly of the side rails thereof at n and to the rear end of the truck frame at n and inwardly of the top rails thereof, and said bed is also provided at the rear end thereof with the usual discharge n. l A

One of the chief features of this improvement is in themethod of arranging the lever arms e and f and connecting them in transverse pairs with the shafts g, the wheels gof which are movable on the tracks or ways [13, and in the pivotal connection of the lever arms f with the hanger plates-e and the sliding and pivotal connection of-the lever arms 6 with said plates-which tog-ether with the method of arranging the chains of cables 5/ and connecting them with the shafts 9 enables the winding mechanism of the hoisting or lifting apparatus to be operated with the least possible exertion of power, and "the said arrangement of the 16'- ver arms and f also enables said lever arms to firmly brace and support the bed in its elevated position. It must be understood, however, that my invention is not limited to the use of the sleeves g on the shafts 9, nor to the placing of the lever arms of each pair in'the same plane, nor to the method of connecting the pulleys g with said shafts as herein shown and described, and said shafts may be made of any desired strength without the use of said sleeves and said pulleys may be connected with said shafts in any desired manner, all that is necessary being that they be suitably spaced thereon, and various changes in and modifications of the construction herein described may be made within the scope of the appended claims, without departing from the spirit of my invention, or sacrificing its advantages.

Having fully described my invention, what I claim as newand desire to secure by Letters Patent, is

1. In a vehicle of the class described, a truck frame, a bed mounted thereon, and a hoisting mechanism for said bed, said hoisting mechanism consisting of a transversely arranged main shaft mounted centrally of the truck said shaft, downwardly and forwardly, and downwardly and backwardly inclined tracks or ways on the inner sides of the opposite sides of the truck frame and forwardly and backwardly of said main shaft, transversely arranged supplemental shafts having wheels mounted on said tracks or ways and placed forwardly and backwardly of the main shaft, a pair of lever arms mounted on each end of said supplemental shafts, one of said lever arms of each pair having a pivotal connection with the bottom of the bed and the other lever arm of each pair having a sliding connection with the bottom of the bed between the said pivotal connection of frame and means for operating hoisting mechanism for said bed, said hoisting mechanism consisting of a transversely arranged main shaft mounted centrally of the truck frame and means for operating said shaft, downwardly and forwardly, and downwardly and backwardly inclined tracks or ways on the inner sides of the opposite sides of the truck frame and forwardly and backwardly of said main shaft, transversely arranged supplemental shafts having wheels mounted on said tracks or ways and placed forwardly and backwardly 0f the main shaft, a pair of lever arms mounted on each end of said supplemental shafts, one of said leverarms of each pair havlng a pivotal connection with the bottom of the bed, and the other lever arm of each pair having a sliding connection with the bottom of the bedbetween said pivotal connection of the first named lever arm of each pair and the transverse middle of the bed, means involving said main shaft for operating said supplemental shafts and said lever arms to raise and lower the bed, devices for preventing the bed from moving forwardly in the operation of raising and lowering the same and devices for supporting the front end of the bed when the rear .end portion thereof is empty.

In testimony that I claim the foregoing as my invention I have signed my namein presence of the subscribing witnesses this 10th day of September 1912.
